include/asm-generic/page.h: calculate virt_to_page and page_to_virt via predefined macro
On NOMMU architectures, if physical memory doesn't start from 0,
ARCH_PFN_OFFSET is defined to generate page index in mem_map array.
Because virtual address is equal to physical address, PAGE_OFFSET is
always 0. virt_to_page and page_to_virt should not index page by
PAGE_OFFSET directly.
